Problems solved by technology

This method is relatively simple and cannot accurately eliminate heading jitter
Or, use complex algorithms such as Kalman filtering, etc., but these complex algorithms are difficult to implement with programs, and need to adjust coefficients based on a large number of experiments, increasing the cost of experiments

Embodiment Construction

[0080] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0081] Please refer to figure 1 , figure 1 It is a flow chart of a filtering method for eliminating heading jitter according to an exemplary embodiment. Such as figure 1 As shown, the method may include the following steps.

[0082] In step 11, the heading sample value is obtained.

[0083] During the sailing process of the ship, the course of the ship can be collected in real time or periodically by using the positioning equipment installed on the ship, such as a GPS positioning antenna, and recorded as the course sample value, wherein the range of the course sample value is [0° , 360°], and the preset direction can be set as the heading 0° direction, a...

Abstract

The invention relates to a filtering method and device for eliminating course jitter, a storage medium and an electronic device. The filtering method comprises the steps that a course sampling value is obtained; the course sampling value obtained this time is input into a first-order low-pass filtering model, and a course filtering output value corresponding to the course sampling value this timeis obtained. By adopting the technical scheme, by considering that the course jitter has the high-frequency variability and the course is a one-dimensional variable, the first-order low-pass filteringmodel is selected cleverly to filter the course sampling value, and thus the course jitter can be eliminated. In this way, the method for eliminating the course jitter is simple, and the accuracy ofeliminating the course jitter can also be ensured.

Description

technical field [0001] The present disclosure relates to the technical field of ship navigation, and in particular, to a filtering method, device, storage medium and electronic equipment for eliminating heading jitter. Background technique [0002] When a ship is sailing at sea, due to factors such as sea waves, tides, wind and rain, the ship's hull is irregularly bumped, causing the positioning equipment (for example, GPS positioning antenna) on the ship to swing, resulting in irregular headings collected by the positioning equipment. shake. The course jitter will affect the judgment of the navigator or other instruments on the actual course of the ship, and then cannot accurately judge whether the ship is yaw, and cannot accurately avoid collisions with obstacles, affecting the safety of ship navigation. [0003] In the prior art, a simple method of calculating an average value or subtracting a jitter error is used to eliminate heading jitter, wherein the jitter error is ...
